Genomics for Diagnostically Challenging Melanocytic Lesions

Expires January 22, 2021

Presentation

Video length: 48 minutes

Melanoma is a potentially lethal cancer that can be completely cured if detected early and treated appropriately. The Mayo Clinic Department of Laboratory Medicine and Pathology has a large consultative practice in dermatopathology. Most diagnostically challenging cases can be classified based on expert review of features observable with light microscopy, but some cases require ancillary testing. This lecture will describe the currently available ancillary testing offered in the Genomics Laboratory and review the genetics of malignant progression in melanocytic lesions.

 

Objectives

Upon completion of this activity, participants should be able to:

  • Define four genomic subtypes of melanoma according to definitions established by The Cancer Genome Atlas network.
  • List two signaling pathways associated with progression to malignancy.
  • Contrast the utility and limitations of FISH and array testing for melanocytic lesions.

 

Intended Audience

This program is appropriate for clinicians, pathologists, medical technologists, nurses, pharmacists, and other allied health staff.
